Question about Canon Pixma MP500 All-In-One InkJet Printer
The printer is just over 12 months old. I've replacedthe ink cartridges once with the correct Canon cartridges and its worked fine for a few months. But now the printer comes up with the code U150 and the message "the following ink tank cannont be recognized"refering to the magenta cartidge. For a while we could fix it and still print by opening up the top and either removing the cartridge or just clicking it. It would then light up like the rest of the cartridges and the message would go away. Sometimes the message was different and it said that there were two cartridges of the same colour - which there wasn't. But we could still solve it the same way. The print quality was always very good and there seemed to be no other problems.
A week ago it stopped cooperating and now the message (U150) won't go away and the printer will not print. Can you give me any idea of what the problem is?
Hey- i just wanted to say that I had the same problem with my MP600. Unlike some people, I have a problem buying ripoff cartridges from a store. I use my printer alot and I simply refill these. You can buy any refill kit and especially with these cartridges, drill a hole near the top and just fill it and plug it. The sponge sucks it up and you're all set. As far as the Chip problem-it is a pain in the ass and the **** at Canon probably won't fix it. HOWEVER, if you still want to print and don't mind that your ink counter says that you are empty simply hold the "STOP/RESET" and the "Black" print button together until it clears and you'll be set. I do it all the time and I know it works on the later MPs. Check it out and stick it to the man

For iP Series Printers: Holding the
paper feed button down for 3-5 seconds will allow you to override the
counter. The cartridge will print , however the ink level display may
For MP Series Printers: Holding the STOP/RESET button down for 3-5 seconds will allow you to override the counter. The cartridge will print, however the ink level display may not show.

I encountered the same problem (U150 Error) with my PGI-BK ink for the first time. I have used my Canon MP500 printer for more than 3 years & never had any issues. I called Canon support & the agent was very helpful. He helped me with few troubleshooting steps, which did not help. But in the end, he said that he is going to ship me a new ink tank as replacement.
BTW, holding the STOP/RESET button does not work on my MP500. How come it worked for 'urbanant' above (see Solution #2). Has anyone else made it work for PIXMA MP500?

My trouble was the same with cyan. Cleaned chip contacts with an eraser. Error remained. Held reset for 10 seconds. Error. Held reset and black for 10 seconds. Error. Opened cover. Print head went across from right to left with three "good" tanks UNLIT and problem tank lit. Then went back to the right and disapeared and then returned to center with all four tanks lit. Printer than printed normally with no error message.???

I called through to the techs, it's a faulty cartridge. They go through this whole lengthy thing to make sure it's nothing else - took me about 15 minutes on the phone, then they mailed me a replacement cartridge, free of charge.
This is apparently something they are dealing with a lot, so call and get your free cartridge replacement.

The problem is due to faulty chip at the bottom of the cartridge. I notice that some chips looked very scratchy, and they are the ones that usually contribute to the u150 problem. Simply buy the canon ink until u get unscratchy chip for each color, and then do not throw away the good chips. If in the future u unfotunately got an ink cartridge that has faulty chip, u can use cutter or knife to pluck out the scratchy chip and use the old unscratchy one that u have kept. However, u will not be able to monitor how much ink is left, but still it is better than having u150 error almost everytime u want to print. Hope this solves the problem

Sometimes it helped me by just unplugging the power. Probably the connection pads to the cartridge are in bad shape, and as soon as one connection is isolated, the printer gets the error message.
